To all 'uflzom it may concern: Be it known that I, HANS EDUARD THEISEN, a citizen of the United States of America, residing at Elisabethstrasse 34, Munich, Germany, have invented certain new and useful Improvements in Apparatus for Cleaning, Cooling, and Washing Gases, of which the following is a specification.

The present invention relates to an apparatus of simple construction, adapted for the cleaning, cooling and washing of gas.

The essence of the invention resides, first, in the provision of lateral washing surfaces, arranged concentrically about outwardly opening fan or propeller. blades, against and upon which surfaces the finely comminuted washing fluid is thrown, the gas being pressed or forced against the layer or stratum of fluid on these surfaces, whereby a thorough cleansing of the gas is accomplished. The gas passes out of the apparatus through the casing proper, which is connected with the said washing surfaces. When the apparatus is constructed in the manner above briefly outlined, the fan or propeller blades are preferablyarranged at such an incline or slope, that the mixture of gas and fluid sucked into the apparatus is thrown, as nearly as may be, at right angles to and against the said washing surfaces.

It is also an important feature of my invention to give the blades substantially the form of plow shares 2'. e. of curved formation, and to inter-twine the blades at their inner parts, which construction results in enhancing the effect of throwing the gas against the lateral washing surfaces. It is advisable to provide the blades with openings or perforations to prevent finely comminuted particles tar and like incrustation from settling in the angles and corners of the blades.

The cleaning action resulting from throwing the gas against the lateral washing sur-' faces is materially increased by providing conduits in communication with these surfaces, whereby. the solid and fluid substances are separated, the cleansed gas being thrown This arran ement-results in a savin of a radially, bycentrifugal action, while the cleansing fluid with its contained impurities passes into and out through the conduits.

power, and also makes it possible to inject water or absorption media into the cleansed gas for the purpose of cooling or absorbing the same, this water or absorption media passing out separately from the cleansing fluid originally action of the blades, the latter may be subdivided or separated by suitable partitions.

The thoroughness of cleaning, mixing and cooling the gas may be increased, by pro viding in the suction chamber of the apparatus a plurality of perforated cylinders or cones, one within the other, these cylinders being rotated in reverse direction, or some of the cylinders being stationary and others thereof movable with the movable parts of the device.

Several forms of the invention are illustratively exemplified in the accompanying drawings, wherein Figure 1 is an end elevation, partly in section, and Fig. 2 a side elevation, partly in section, of one form of the invention; Fig. 3 is a vertical section of a modified form; Fig. 4 is a transverse section taken on the line A--B of Fig. 3; Fig. 5 is a similar view taken on the line CD of Fig. 3; and Fig. 6 is a fragmentary view of the blade carrying disk.

Referring to the drawings, it Will be noted that I provide apaddle or propeller wheel 6, the paddles F of which are open laterally and at their inner portions are shaped like plow shares 2. e. curved so that they throw the mixture out laterally with great force. To increase the force of this action the blades are preferably smallerat their outer than at their inner portions, and the walls of the casing, below the gas discharge channel 0 may be contracted, so that there is formed laterally of the paddle wheels, entirely surrounding the same and spaced :1 short distance away therefrom, an

inclined washing surface M from which the mixture thrown against the same runs off to be conducted out of the apparatus. In order that this mixture may not run back into the discharge channel 6 or into the apparatus casing, I provide, concentrically with the'outer edge of the surfaces M, a conduit f intowhich the admixed solid and fluid enters and passes out of the apparatus at g. At the outer end F the paddles are extended beyond the inner edge of the conduit f and are preferably closed laterally, and arranged parallcl to the shaft a, so that these paddies operate in the usual manner of blades or fans to force the gas into the channel 6.

employed. To intensify the 5'5 surfaces each 0 designates jet pipes through which absorptio'n or cleansing media is injected into the apparatus.

E and E are the gas admission ports and G is the gas emisslon port.

In the form of invention just described, the. solid and fluid constituents, such as cleaning water, tar and'oilpass into the conduit f separate from thegas which passes 0 outthroug the discharge channel e. If therefore'itis desired to subject the cleansed gas to 'further treatment,- additional jet pipes '11 dischargingxin to the channel 0 may provided, and t rough these pipes may be njected any substance for c00l1ng,.ab-

aorbin or further cleaning the .gas, the

' latter ing finally discharged at G and the material used. for such add1tional treatment passing out of the casin at i. In this connection it is to be note that the form of invention of Figs. 1 and 2 may be further somodified that the blades are double acting, that is to say, they may be arranged to act ..1,.;against two. op sitly disposed washing which is' provided with a conduit. When the structure is so modified the blades are carried b a central supporting disk b.. Fig. 3 s own an apparatus wherein there are two such conduits f, each terminating in an outlet port 9. Furthermore Fig. 3differs from the structure of Figs. 1 and 2 in that suitable partitions F ,ane ar'ran ed between the blades, these partitionsia' mg in preventin radial, and cans- 5 ing lateral, discharge of t e gas and fluid.

Therexare also provided in the suction chambet. oi the ap aratus, disintegrators m and mlwhich e erably consist of perforated sheetmeta orwire "mesh concentric cylin- 40 data or cones, one the other, certain of these cylinders bein relatively fixed and others thereofbeing a apted to rotate with the paddles; "These cylinders or disintegrators serve to thorou hly admix the gas with 4.5 the abso tion or c eansing fluid admitted through t e jet pipes 0.
